Littelfuse SPA SRV05 Series ESD Protection Diode, SOT-23, 6-Pin, 15V

The Littelfuse SPA SRV05 Series is a 6V, 10A transient voltage suppression (TVS) diode array designed for robust ESD and surge protection in sensitive electronic circuits. This advanced component integrates low capacitance rail-to-rail diodes with an additional Zener diode to safeguard each I/O pin against electrostatic discharge (ESD) and high-energy surge events, making it a critical defence mechanism in modern digital and communication systems.

Engineered for reliability, it meets stringent international protection standards. It provides protection against ESD events up to ±30kV (both contact and air discharge) as per IEC 61000-4-2. It also defends against electrical fast transients (EFT) of 40A (5/50ns) per IEC 61000-4-4 and lightning surges of 10A (8/20µs) in compliance with IEC 61000-4-5 2nd Edition, ensuring your equipment can withstand real-world electrical threats.

A key feature is its exceptionally low leakage current of just 0.5µA (max) at 5V, which minimises power loss and is ideal for power-sensitive portable applications. With a maximum clamping voltage of 15V and a power dissipation rating of 150W, it effectively suppresses overvoltage transients to safe levels, preventing damage to downstream components.

Primary Applications

This versatile protection device is suitable for a wide array of consumer and industrial electronics, including LCD and PDP televisions, computer monitors, notebooks, and flat-panel displays. It is also perfectly suited for protecting high-speed data interfaces such as 10/100/1000 Ethernet ports, FireWire connections, and set-top boxes. Furthermore, its reliability makes it an excellent choice for sensitive portable medical equipment where signal integrity and patient safety are paramount.

Housed in a compact, industry-standard SOT-23 package with 6 pins, it offers an efficient protection solution without occupying significant board space, facilitating easier PCB (p.c
